Fixed-Gear or Singlespeed?

"Fixed Gear" means a one-speed bike where the pedals move whenever the bike moves. You can't coast on a fixed gear, but it has real advantages. For lots more information about fixed gears, click here. We generally use the term "singlespeed" to refer to a one-speed bike with a freewheel, that is a bike that can coast without the pedals moving. For lots more information about singlespeed "coasties" click here. The wheels shown on this page have three different types of hubs:

Hub Spacing and Chainline



The "spacing" refers to the space between the fork ends. Different frames have different spacing in back, anywhere from 110 mm to 135 mm or more. The width of the hub (usually measured from the outer faces of the locknuts) needs to match the frame spacing.

Most of the hubs we sell can be modified to fit wider spacings by adding spacer washers between the cones and locknuts. It is also possible in many cases to adjust the spacing of the frame itself. See my Frame Spacing Article for details.

In general, mountain bikes will have 135 mm spacing, "road bikes 120 to 130, depending on their age, and track bikes 110 to 120 depending on their age. If in doubt, you should measure:


This frame has a spacing of 125 mm

The spacing of a hub is measured from the outside faces of the cone locknuts, where they come into contact with the frame's fork ends. (Most cartridge-bearing type hubs don't have locknuts, so the spacing is measured from the equivalent shoulder surface of the axle ends.) The spacing dimension is commonly referred to as the "O.L.D." (Over-Lock-nut Distance)


The chainline is the horizontal distance from the centerline of the frame to the centerline of the chain. One of the major advantages of singlespeed and fixed gear bikes, as opposed to bikes with derailer gearing, is that the chainline is straight. This makes for a more efficient drive train (less friction, better power transmission.)

To ensure good chainline, you need to make the front chainline (distance from frame center to the center of the chainring teeth) match the rear chainline (hub center to the center of the sprocket.) Generally you would want to get this within a millimeter or maybe two of the same front and rear.

For details, see my article on Chainline.

If you're using a "road" or "track" type frame, you are best off with a typical "track" chainline of about 42 mm. Most of the "track" hubs we feature will give a chainline in that vicinity.

If you're using a "mountain" type frame, however, 42 mm chainline usually won't work, because most mountain bikes have wider chain stays, so you generally can't fit a reasonable sized chainring that close in. For that reason, singlespeed "mountain" bikes usually use a 52 mm chainline, or in some cases, 47 mm.
